shown and deserlhedin said patent, referwith 1.115); y l y l lfVor/'dpz'ndle beoihamsin;

et af editable dietance below the forming 'slides 6 and at a suitable'distance from each other, and in gable formation, are housed the workspindles 9, eight in number, being located in Sets of'four, one setateach eide4 of the' center of the machine. These spindles and theirbearings Irre likewisesimilar to those shown and deseribediin saidpatent, end therefore, a' detailed description thereof herein is notdeemed necessary.

Located above and in parallel with-the Work spindles, and likewise ingable formation, are rotatably housed auxiliary shafts 10. vHoused in asuit'- lielieal gears "I Ljand these shafts-and gears are held 1n.position against endwise movealineinent l l 5 vence thereto is made fora more particular description thereof., (eee p 4 eimlymen'cing N-OY mentby suitable split spacing collars pro- -vided with suitable bolts andthrust' Washers, which are `housed over the' shafts between the collarsand lnner face of a bed trame..

In mesh with the twov uppermost spiral gears, one at each side, ie themam splndle drive geanl (see Fig. 2) This gear is keyed to the maindriveshaft 1.3, whrehhas its bearing in the bed portions 3 and 4. Keyed tothis drive shaft 13 and resting against the inner face of the bedportion a is a miter gear 14. Secured to the work spindles are the-workspindle gears 15, (see Fig. 6) and as there are four spindles on eachside, there 'are likewise four gears on each side, the two lower gearson each side being in mesh with each other and the two upper gears oneach side also being in mesh with each other. Mounted on a stud 16y ateach side of the machine is an intermediate fdrive Gear 17, which is inmesh with the two middle or'the second and third gears vof each set offour spindle gears, thereby to vrotate these two middle gears, which inturn rotate their companion gears and thus drive the four work spindles.`Each intermediate gea-r 17 is in mesh with a gear 18 carried bythelower spiral gear spindle or shaft 10, so that when the two sets ofspiral gears 11 are driven the work spindles will be rotated. On topl ofthe apex portion 2 of the gabled bed is suitably mounted a motor Mprovided with a spur gear 19, which meshes with a spur gear 2O mountedon the drive shaft 13, and in conjunction with suit-l able change gears2,1 located between this spur gear 20 and the face of the bed pro videsthe desired changes in speed for the work spindles. This change gearsystem 'is similar to that commonly used in National Acme machines, andtherefore no further explanation thereof is deemed necessary hereinsince it will be obvious that when the motor is started the workspindles will be rotated through the medium of the spiral gears andcooperating gears at the desired speed.

Worm and camszaft mechanisms.

lMounted in a vertical hearing at the inside face ofl the bed portion a(see for instance Figs. 2 and 6) is a. vertical shaft 22 to the upperend of which is keyed a mitci' gear 23 1n mesh with the mite-r gear lacarried by thev drive shaft 13 see Fig. 2

To the lowei' end ofths shaft is a similar niiter gear 24 in mesh with asimilar gear 25 carried by an angularly located `shaft 26 mountedinsuitable bearings carried by the' bed, these two shafts 22 and 26forming in-l tei-mediate shafts between the drive shaft 13 .and the'worm shaft hereinafter described. To the lower end of this shaft 26 is amiter gear 27 in mesh with a similar gear.v 28 mounted on the worm shaft29,

As this worm shaft and its cooperating mechanism including the mainchange gears for varying the speed of he cam shaft are substantiallyidentical with those shown and described in the patent hereinbeforereferred'to, a detailed description thereof is not deemed necessaryherein, escept to say that vthe change gears are shown at 3Q (see Figs.1 and 6) being located at one end of the worm shaft, while thecontrolling mechanism 31 for the machine (sec Fig. 2 is located at theother end thereof.

Mounted in suitable bearings of the bed centrally thereof is a cam, shatt (see Fig. This shaft has suitable end thrust bearings likewisesimilar to those shown `and described in the patent -hereinbeforereferredto. Keyed adjacent to oneeiidv of this cani shaft and inposition to mesh with the worm 33 on the worm shaft is a Worm gear 3a.This worm gear is con.- nected with one of the main camdrums of the camshaft, for instance what may be termed the lead cani drum, which iseffective to operate. the drill slides.` llfhis connection thus forms adirect drive between the worm wheel 34 and the cam drum, and is in theform of safety mechanism (sec F ig. 13). This mechanism comprises meansfor driving the cam drum directly from the worm gear, and this fromsubstantially the outer periphery of the worm gear to substantially theouter periphery of thecani the cam shaft 32, bein suitably keyedthereto, and also pinned tl loreto. This cam drum is counterbored at 33to receive the outwardly flaring connecting members or arms 39 of thering shaped member a0, the arms 39 being bolted to the cam vdruni as at41.

The worm wheel 34 is shown comprising a hub portion 36 loosely mountedupon the v9() drum, The cam drum 37 is mounted upon cam shaft 32, whilethe worm wheel proper 34.- comprises a bronze ring or 'rim having`suitable teeth on its pei ihery adapted lto mesh with the worm geai` 33.This worm ring is suitably secured or bolted to a flange of the hubportion 36 as at 42. 'lhe'iiangedportion of the hub 3G is connected withthe ring-shaped member i!) carrying the arms 39 by suitable safetydevices or `pins 43.

Thus it will be seen that on the rotation of,

, chine, in the event that a strain greater than the safety pins willstand isv placed upon any part of the mechanism operated through themedium of the cam shaft, theselpins will shear, and inasmuch asthe soleconnection between the worm wheel on the one hand.

and the cam drum on the lother hand. is through the. 'medium of ,thesesafety pins,

it follows that the worm wheell on the sliearor the cam shaft.

ing of the pins may continue to rot-ate with out imparting any motion tothe cam drum Itis not necessaryv to describe hereinV in detail the camdrums and discs or the cams and cam straps carried by the drums, 'sincethe -construction and purpose of these parts are well understood inmachine shop practice, it being merely necessaryto say that theparticular shape and style of cam and suitable distance apart` and' inparallelism with each other and'with'the work spindle. 0n these bars 45are slidingly mounted thewedge locking slides 46,-four in number, two oneach side of the machine (see for instance s. 3, .5 and7). ."heseslides'are of a length suicient to l peinit them to travel back .andforth a' Apreideterniined distance on the slide hars 45.

-From an inspection ofFig. 7 it will be seen that theseslides are soconstructed at each sideof the machine that each receives or haspassingrtherethrough one of the three slidbars 45, while the middle slide barAis received orpasses through the pair of slides 46; In other words, thejuxtaposed `side faces ofA the pair of slides are semicircularly formedso that the middlek pair 45 receives both slides, as at 47. Thus, theouter slide bars/45 on each side of themachine rece'ive the full bore ofthe slides while the center ofthe three bars 45 receives approximatelyone-halfof the cil-cular bore of the two slides;4 To the lower faces ofeach pair of yslides 46 aregfastencd suitable studs and rollers 48, onestud and roller foreach slide,

these rollersbeiiigA located in such position k'by the slides .46l-ivillrbe shifted back and forth. The'iip'per lfaces of vthe slides 46are fas'to'coine incontactwith'duplicate sets of cams 48 on a-'cam drum'46 carried by the cani shaft 32r at a predetermined time whereprovidedwithl suitable notches or depressions 50 (see Fig, 3) to receive thelower cirjf`l p cularlyfformed ends of the wedge levers S,

rods '44 at the front end of the machine are a vpair of end tool slides51, one at each side'- o-the machine in front of the Work s ,indles .andthe side working orforming too slides.v Thus, as the work rods are 'fed'throughl thev work spindles from the rear of the machine toward theA.front thereof for the operation of the side ,workinrlr toolsearried'by the tool slides 6, they will ated upon by the end wor ingtools inclu ing thev drills lcarried by the drill slides. This pair ofdrill slides, each fastened to a pair of pull rods44, are likewisevlocated in gable 'or A-sliaped formation corresponding with I' thelocation ofv the work spindles, there being one drill for instance foreach work spindle.` The construction of these end working tool slides isinthe main substantially similar lto the construction of those set forthand de.-

scribed in the prior application andl atent liereinl'iefoi*y rel ved to,and there ore a detailed desiriptnm 'thereof is not-deemed necessaryherein, it being merely necessary to say that each slide is providedwith semicircular bores, into which are housed the drill holders 68,which are seouredin posi-.

From the foregoing` it will h seen that,

e notwithstanding the increa ed sii/,e ot' the machine and the workii'igparte to adapt the machinelto large work, notwithstand ing,r theincreased numher olV work'spindles vand tools, the construction is suchthat the. spindles and 'tools led "very small space, making hie to useon)7 onencam shaft'and i ssihle, notwithstanding the increase@ c oil theparis and the additionall work spin des, to materially reduce the sizeor width of the machine, even -for large work, and also making itpossible to operate the machine much easier and making,r it handier toget at.

Furthermore, the present construction provides `tor a center drive,since the motor is located on top ot the machine centr: lly ot the Widththereof, whereas in the prior machines hereinbcftore referred to, theinotor Yas at the side ot' thev machine and therefore the drive was nota central one. 'lhese are but some oi" the additional advantages for thepresent improved machine, and all of which make for increased and moreeen noinical production oi' the product, as well as more accura eresults.

it will be observed that the side forming" tool cam mechanism, the endWorking tool cam mechanism and the chuck operating tool mechanisn'i Jforthe work spindles are each duplicates, and are located, as it were, one,behind the otheron the cam shaft, one oi each conti-oliing'` itsoperated parts at one side of the machine, while the. other controls itsoperated parts at the other` side ofthe machine, and that ashereinhefore. stated, the side w rking tools, the end working tools, thework spindles and thev several shdes and operating mechanisms controlledby the cam shaft areall locaced in gable formation with the side workingtools in gable triangular formation above the gable 'forma-tion of theend working tools and work spindles, which improved construction, ashereinbefore stated., makes possible an additional niunbel' -of workspindles and cooperating tools, consequently an increased orodnction ofproduct, while at the same imc reducing' the width or size of themahine, and also makes possible the use of a single cam shaft mechanismand a. central drive located, as it were, at the apex ofthe machinel` Itis to be understood that by ldescribing in detail herein any particularform, structure, or arrangement, it is not intended to limit theinvention beyond the terms of the several claims or the requirements ofthe prior art. v y
